Laptop shuts off when AC adapter plugged in Problem description:
The laptop shuts off when AC power adapter is plugged in. The laptop works fine on battery power but as soon as you connect it to AC adapter, the laptop turns off. Possible cause:
1. Power adapter failure. 2. Motherboard failure.
Possible troubleshooting steps and repair solution:
First of all, test the power adpater. Make sure the apdapter outputs correct voltage. It's possible that the outup voltage is not correct and the laptop shuts down to prevent the damge. Test your laptop with anohter known good power adapter.
If the problem still exists, even after replacing the adapter, most likley it's the motherboard failure. Replace the motherboard
Try pulling out the cmos battery and holding down the power button for 15 seconds see if that clears the bios settings, if not do a search on line for *********** board jumper settings and you should get some thing.
An attractive value of dualcore processors is that they do not require a new motherboard, but can be used in existing boards that feature the correct socket. Check sockets if same then enjoy.
I don't think that you motherboard supports Core 2 CPU,but you can't neglect the chances.Before buying ask the retailer about the sockets matching.
here's a site that sells motherboards for your system ...... about 200.00 but you are paying for the labor to install , unless you can do it yourself ?! Are you sure the last one is gone ? do you have warranty ? motherboards have a decent warranty that comes with purchase , also the place you had it repaired should have a years warranty on there work ?! and they would also get the rma on the motherboard .
Is your PC beeper connected and does it gove you any error beeps when you power on (before POST)?
Firstly, ensure you have purchased the correct RAM for your system.
Do you know the model number of your mainboard?
Do you know the model number of you RAM?
Can your MB handle the amount of memory you are installing?
If you give me the model numbers I can check compatablilty for you.
If you KNOW you have purchased compatible RAM, then make sure you have installed in correctly (a very common error, even with myself and very experienced techs). Don't be scared to give them a good push when you install the DIMMs. The locking arms should postion and 'lock in' by themselves.
Are you installing 1 stick or 2 x matched pair?
Are you adding new sticks to existing sticks? If so, remove the old sticks and have only the new sticks in? If this doesn't work then put just your old (working I assume) RAM.... does it work?
Try not to mix RAM types in matched slots.... this can cause conflicts sometimes.
If you're getting this message during the POST and there are IDE drives then chances are you haven't configured the drives correctly.To correctly configure two drives on an IDE channel you need to either:
- have one drive set as Master (using jumpers on the back of the drive) and the other as Slave OR
- have both set as Cable Select (CS) with the appropriate cable.
If you are unsure how to proceed look at your original drive and let us know how the jumpers are currently set.
